merging changes
And Bob does the same...
Bob finished up the tasks related to his story and ran a quick test on his end. His task
is working, so he copies his code up to the server. In order to do the final build he
merges his code in with ours, gets everything to compile, and retests sending a picture.
Everything looks good. Tomorrow’s demo is going to rock...

Q: I’m not familiar with networking code. What’s
happening in that code we just added?
A: On the sending side we represent the sequence settings
as an array of checkboxes. We don’t really care what they’re set
to, since we won’t use them on the receiving side. We still need
to send something, though, so the existing code works. We use
Java’s object serialization to stream the array of checkboxes
and our secret message that triggers the alert on the other side.
On the receiving side we pull off the secret sequence and the
array of checkboxes. All of the serialization and deserialization
is handled by Java.

Bob’s happy with the code so he copies it
up to the demo server. After the build is
done, things are ready for tomorrow.

Here’s Bob’s version of
BeatBox—the SendPicture
button is implemented.
Q: Why did we make the bin directory before we
compiled the code?
A: We’ll talk more about this in the next chapter, but in
general it’s a good idea to keep your compiled code separate
from the source. It makes it a lot simpler to clean up and rebuild
when you make changes. There’s nothing special about the
name “bin”; it’s just convention and is short for “binaries”—i.e.,
compiled code.
Q: Wait, did Bob just merge code on the demo server?
A: Yup...
